FIELD OF THE INVENTION

The present invention relates generally to media content, and more particularly, to a system and a method for edge caching media content on an infotainment device in an automotive environment.

BACKGROUND

Generally, commuters utilize different modes of transportation to travel between two or more locations. For example, a commuter may prefer either a public mode of transportation or a private mode of transportation to travel between a source location and a destination location. Such traveling activities of the commuters have led to a significant increase in the demand of the different modes of the transportation. With the increase in the demand of the different modes of transportation, various transportation service providers are adopting various schemes to attract the commuters to use their services. Generally, these schemes focus on safety, efficiency, savings, and comfort level of the commuters. Some of the transportation service providers have further installed entertainment systems in their vehicles, i.e., an in-vehicle entertainment system to provide a pleasant and joyful ride experience to the passengers. Such in-vehicle entertainment systems may include a vehicle head unit, one or more inbuilt speakers, and one or more display screens for playing media content. The media content is downloaded, and stored offline in a storage device that is either embedded within or is external to the in-vehicle entertainment systems. However, since the media content available for the playback is limited due to a limited storage capacity of the storage device, overall entertainment experience of the commuters during the travel is compromised.

To encounter the limited storage capacity of the storage device, some in-vehicle entertainment systems play the media content that are received through broadcast signals in real time or near-real time. However, the broadcast signals may get affected due to poor connection over a network, which may further affect the playback of the media content. Hence, the overall entertainment experience of the commuters in the vehicle is further compromised. In such scenarios, the commuters may be required to carry various media storage devices, such as compact discs (CDs), Universal serial bus (USB) drives, flash drives, and the like, having stored media content of their interests and preferences that would be played by the in-vehicle entertainment systems. This becomes very inconvenient for the commuters.

Hence, it would be advantageous to have the in-vehicle entertainment systems for the different modes of transportation that does not require the commuters to carry any additional hardware devices, and furthermore, provides relevant media content that will enhance the experience of the commuters.

SUMMARY

In an embodiment of the present invention, a system for edge caching media content is provided. The system includes a first device placed in a vehicle. The first device includes a memory and circuitry. The memory is configured to store the media content. The circuitry is configured to receive a first request to commute between a plurality of locations. The first request is received from a commuter device of a commuter via a first communication network. The circuitry is further configured to extract the media content including a first set of media content and a second set of media content from a database server via the first communication network. The first set of media content and the second set of media content are extracted based on a set of rules in response to the received first request. The circuitry is further configured to store the extracted media content in the memory. The circuitry is further configured to control a playback of the media content from one of the stored first set of media content or the stored second set of media content on an output device of a second device in the vehicle. The playback of the media content from one of the stored first set of media content or the stored second set of media content on the display screen is controlled based on a second request by the commuter in the vehicle.

In another embodiment of the present invention, a method for edge caching media content on a first device placed in a vehicle is provided. A first request to commute between a plurality of locations is received by the first device from a commuter device of a commuter via a first communication network. In response to the received first request, the media content including a first set of media content and a second set of media content are extracted by the first device from a database server via the first communication network. The first set of media content and the second set of media content are extracted based on a set of rules. The extracted media content is stored in a memory by the first device. A playback of the media content from one of the stored first set of media content or the stored second set of media content is controlled by the first device on a display screen of a second device in the vehicle. The playback of the media content from one of the stored first set of media content or the stored second set of media content on the display screen is controlled based on a second request by the commuter in the vehicle.

Various embodiments of the present invention provide a method and a system for edge caching media content in an automotive environment. A first device placed in a vehicle receives a first request from a commuter device of a commuter via a first communication network. The first request corresponds to a request to commute between a plurality of locations. In response to the received first request, the first device extracts the media content including a first set of media content and a second set of media content from a database server. The first device is connected to the database server via the first communication network. The first set of media content and the second set of media content are extracted from the database server based on a set of rules. The first device determines the set of rules based on a fixed type and a dynamic type of the media content.

The fixed type of the media content corresponds to the first set of media content including fixed media content that is stored in the memory. The first device determines the fixed media content based on at least one of safety-related media content and trending media content. The trending media content is associated with at least one of music, movies, sports, and newscast of one or more events in one or more regions. The dynamic type of the media content corresponds to the second set of media content including dynamic media content. The first device further determines the dynamic media content based on at least one of regional preferences, commuter preferences, and watch history of the commuter. The first device further extracts the first set of media content and the second set of media content from the database server based on a segmentation of the media content in the first set of media content and the second set of media content. The first set of media content and the second set of media content are segmented based on at least one of the watch history of the commuter and a journey time between the plurality of locations. Based on the segmented media content, the first device extracts the first set of media content and the second set of media content from the database server that are significant with respect to the commuter. The first device further extracts the first set of media content and the second set of media content from the database server in a time duration that is based on a first time and a second time. The first time corresponds to a time of confirmation of the received first request by the commuter. The second time corresponds to a time of boarding of the vehicle by the commuter.

In an embodiment, based on the extracted media content from the database server, the first device stores the extracted media content in a memory of the first device. The first device further controls the playback of the media content from one of the stored first set of media content or the stored second set of media content on a display screen of a second device in the vehicle. The playback of the media content from one of the stored first set of media content or the stored second set of media content on the display screen is controlled based on a second request by the commuter in the vehicle.

In an embodiment, the second device corresponds to one of the first device, a separate device other than the first device placed in the vehicle, or the commuter device. In case the second device corresponds to one of the separate device or the commuter device, the second device is connected to the first device by means of a second communication network. Further, in an embodiment, in response to a third request by the commuter in the vehicle, the first device performs a real time extraction of the dynamic media content from the database server. The real time extraction of the dynamic media content is executed based on a remaining journey time associated with the received first request. Based on the real time extraction of the dynamic media content, the first device updates the stored second set of media content in the memory. Hence, the first device creates an edge caching of the media content that prevents the commuter to carry any additional hardware devices, and furthermore, provides relevant media content files that will enhance the overall travel experience of the commuters during the journey. Therefore, the edge caching of the media content on the first device of the vehicle provides a pleasant and joyful ride experience to the commuters.

The first processor 202 includes suitable logic, circuitry, and/or interfaces to execute instructions stored in the memory 204. For example, the first processor 202 analyzes the received first request. Further, in response to the analysis of the received first request, the first processor 202 generates the query to extract the media content from the database server 102. The first processor 202 receives and stores the extracted media content in the memory 204 by means of the first transceiver 200. The first processor 202 further receives the second request from the second processor 214 for the playback of the media content selected by the commuter in the vehicle 106. In response to the received second request, the first processor 202 transmits the media content to the second transceiver 212 using the first transceiver 200. The first processor 202 further controls the playback of the media content on the output device 220 of the second device 112 through the second I/O port 216. Examples of the first processor 202 include an application-specific integrated circuit (ASIC) processor, a reduced instruction set computing (RISC) processor, a complex instruction set computing (CISC) processor, a field-programmable gate array (FPGA), and the like.

The second transceiver 212 communicates with the first transceiver 200 via the second communication network 114. The second transceiver 212 transmits the second request provided by the commuter through the second I/O port 216 to the first transceiver 200. In response to the transmitted second request, the second transceiver 212 receives the media content from the first transceiver 200 under the control of the first processor 202. Examples of the second transceiver 212 include, but are not limited to, an antenna, a radio frequency transceiver, a wireless transceiver, a Bluetooth transceiver, and the like. The second transceiver 212 communicates with the first transceiver 200 and the second processor 214 using various wired and wireless communication protocols, such as TCP/IP, UDP, 2G, 3G, 4G communication protocols, or any combination thereof.

The second processor 214 includes suitable logic, circuitry, and/or interfaces to provide the playback of the media content requested by the commuter travelling in the vehicle 106. For example, the commuter selects the media content from a list of the stored media content in the memory 204. In response to the selection, the second processor 214 receives the selected media content from the first device 110, and plays the media content under the control of the first processor 202. Examples of the second processor 214 include an ASIC processor, a RISC processor, a CISC processor, an FPGA, and the like. It will be apparent to a person skilled in the art that the second processor 214 is compatible with multiple operating systems. The second processor 214 plays the media content on the output device 220 by means of a second multimedia player 222. Examples of the second multimedia player 222 include Quicktime® player, Windows® Media Player, Video LAN client (VLC®) media player, RealPlayer®, iTunes®, and the like.

In operation, the commuter device 104 transmits the first request to the first device 110 via the first communication network 108. The first request corresponds to a request to commute between the plurality of locations including the source location and the destination location. The first transceiver 200 receives the first request, and stores the first request in the memory 204. The first processor 202 analyzes the received first request and determines whether a ride has been confirmed based on the received first request. Based on the confirmation of the ride, the first processor 202 generates the query to extract the media content including the first set of media content and the second set of media content from the database server 102. In an embodiment, the first processor 202 generates the query based on a set of rules. The first processor 202 determines the set of rules based on a fixed type and a dynamic type of the media content. The fixed type of the media content corresponds to the first set of media content that need to be essentially stored in the memory 204.

The fixed media content (i.e., the first set of media content) includes the media content, such as, but is not limited to, safety-related media content or trending media content. For example, the fixed media content may include an audio file or a video file of safety-related procedures to be followed by the commuter while riding the vehicle 106. The fixed media content further includes popular media content associated with at least one of music, movies, sports, and newscast of the one or more events that are trending in one or more geographical regions including a current geographical region of the commuter.

The dynamic media content (i.e., the second set of media content) includes the media content that is dynamic in nature i.e., the dynamic media content changes with respect to time based on the commuter. The dynamic media content is determined based on regional preferences, personal preferences, or watch history of the commuter. For example, the dynamic media content may include an audio file or a video file related to music, movies, sports, or newscast of the one or more events that are specific to a region as preferred by the commuter. The dynamic media content may include the audio file or the video file that are related to (or similar to) the media content that has been recently viewed, visited, or liked by the commuter. The first processor 202 determines such preferences of the commuter based on a browsing history, travel history, or social media profile of the commuter. Based on the generation of the query to extract the media content from the database server 102, the first transceiver 200 transmits the generated query to the database server 102 via the first communication network under the control of the first processor 202. In response to the received query from the first transceiver 200, the database server 102 transmits the media content. The first transceiver 200 receives the extracted media content including the first set of media content and the second set of media content, and stores the extracted media content in the memory 204.

In another embodiment, the first processor 202 extracts the media content including the first set of media content and the second set of media content from the database server 102 based on a segmentation of the media content. The first processor 202 segments the first set of media content and the second set of media content into a first set of multiple media content and a second set of multiple media content based on at least one of the watch history of the commuter or the (expected) journey time between the plurality of locations. Based on the segmentation, the first processor 202 retrieves only those segmented parts of the media content that are relevant to the commuter during the ride. For example, based on the watch history of the commuter, the first processor 202 determines that the commuter had watched first “10 minutes” of a short movie “ABCDEF” having a movie duration of “25 minutes” in total. In such a scenario, the first processor 202 may segment the short movie “ABCDEF” into two parts, such as a first part of the short movie “ABCDEF” with “10 minutes” duration that has been already watched by the commuter, and a second part of the short movie “ABCDEF” with “15 minutes” duration that has not been watched by the commuter. After the segmentation, the first processor 202 may extract the second part of the movie “ABCDEF” with “15 minutes” duration, and stores the extracted second part of the movie “ABCDEF” in the memory 204.

In another example, the first processor 202 segments the media content based on the journey time between the plurality of locations including the source location and the destination location. For example, based on the received first request, the first processor 202 determines that the expected journey time between the plurality of locations including the source location and the destination location is “10 minutes”. In such a scenario, the first processor 202 segments a video into two parts, and thereafter, extracts and stores the part of the video with “10 minutes” duration.

In yet another example, the first processor 202 segments the media content based on the watch history of the commuter and the expected journey time between the plurality of locations including the source location and the destination location. Considering the ongoing examples as described above, the first processor 202 determines that the commuter had watched first “10 minutes” of the short movie “ABCDEF” having the movie duration of “25 minutes” in total. The first processor 202 further determines that the journey time is “10 minutes”. In such a scenario, the first processor 202 may segment the short movie “ABCDEF” into three parts, such as a first part of the short movie “ABCDEF” with “10 minutes” duration that has been already watched by the commuter, a second part of the short movie “ABCDEF” with “10 minutes” duration that has not been watched by the commuter, and a third part of the short movie “ABCDEF” with “5 minutes” duration that has not been watched by the commuter. After the segmentation, the first processor 202 may extract the second part of the movie “ABCDEF” with “10 minutes” duration that matches with the determined journey time “10 minutes”, and stores the extracted second part of the movie “ABCDEF” in the memory 204.

In another embodiment, the first processor 202 extracts the media content including the first set of media content and the second set of media content from the database server 102 in a time duration that is based on a first time and a second time. The first time corresponds to a time of confirmation of the received first request by the commuter. The second time corresponds to a time of boarding of the vehicle 106 by the commuter. Therefore, the first processor 202 extracts the media content including the first set of media content and the second set of media content from the database server 102 in the time duration defined by the first time and the second time. For example, the first processor 202 extracts the media content based on at least one of the generated set of rules and the segmentation of the media content, as described above, before the boarding of the vehicle 106 by the commuter. Thereafter, the first transceiver 200 stores the extracted media content including the first set of media content and the second set of media content into the memory 204 under the control of the first processor 202.

After the commuter has boarded the vehicle 106, the commuter provides, by means of the second I/O port 216, the second request to play the media content selected from one of the stored first set of media content or the stored second set of media content. The second transceiver 212 transmits the second request to the first transceiver 200. Based on the received second request, the first processor 202 may retrieve the selected media content from the memory 204. The first processor 202 further controls the playback of the retrieved media content on the output device 220 of the second device 112 based on the received second request.

Further, in an embodiment, the first processor 202 updates the stored second set of media content in the memory 204. The first processor 202 updates the stored second set of media content based on a real time or a near-real time extraction of the dynamic type of the media content from the database server 102. The first processor 202 executes the real time or near-real time extraction of the dynamic type of the media content from the database server 102 in response to a third request by the commuter in the vehicle 106. The commuter provides, by means of the second I/O port 216, the third request including his/her preferences for the dynamic type of the media content. In response to the third request, the first processor 202 executes the real time (or near-real time) extraction of the dynamic type of the media content from the database server 102. The dynamic type of the media content is extracted from the database server 102 based on a remaining journey time associated with the received first request.

Thus, the system environment 100 provides a mechanism for edge caching the media content in the memory 204 of the first device 110 placed in the vehicle 106. The system environment 100 uses a set of request commands exchanged between the first device 110 and the commuter device 104 or the second device 112 for edge caching the media content. Based on such targeted edge caching of the media content in the memory 204 of the first device 110, the memory requirement for the storage of the targeted media content is less, and thus, additional memory requirement for the storage is minimized. Further, the system environment 100 for edge caching the media content on the first device 110 of the vehicle 106 discourages the commuters from carrying any additional hardware devices including the media content of their interests which, sometimes, may cause inconvenience to the commuters. Thus, the system environment 100 does not require the additional hardware devices for playing the media content. Further, the system environment 100 offers another advantage where the commuters travelling in the vehicle 106 has total control over the playback of the media content. With such control, the commuters can provide the request commands to extract the desired media content in the real time or near-real time. Further, the first device 110 is capable of pairing with commuter's personal device, such as the commuter device 104, and thus, the commuter can control the playback of the media content by using his/her personal device.

Referring now to FIGS. 3A and 3B, a flowchart 300 that illustrates a method for edge caching the media content on the first device 110 of the vehicle 106 of the system environment 100 in accordance with an embodiment of the present invention is shown.

At step 302, the first processor 202 receives the first request from the commuter device 104 via the first transceiver 200. The first request corresponds to a request to commute between the plurality of locations including the source location and the destination location. The commuter device 104 transmits the first request to the first transceiver 200 via the first communication network 108.

At step 304, the first processor 202 determines whether the first request has been confirmed. Alternatively stated, the first processor 202 determines whether the commuter has confirmed the first request for the vehicle 106 for a ride between the plurality of locations. If at step 304, it is determined that the first request has not been confirmed, the first processor 202 may receive the first request from another commuter device. However, if at step 304, it is determined that the first request has been confirmed, step 306 is executed.

At step 306, the first processor 202 determines the set of rules. In response to the confirmation of the received first request, the first processor 202 determines the set of rules based on the fixed type and the dynamic type of the media content. In an embodiment, the fixed type of the media content corresponds to the first set of media content including fixed media content. The first processor 202 determines the set of rules corresponding to the first set of media content based on at least one of the safety-related media content and the trending media content that need to be essentially stored in the memory 204. In an embodiment, the dynamic type of the media content corresponds to the second set of media content. The first processor 202 determines the set of rules corresponding to the dynamic type of media content based on at least one of the regional preferences, the commuter preferences, and the watch history of the commuter.

At step 308, the first processor 202 extracts the media content including the first set of media content and the second set of media content from the database server 102 based on the determined set of rules. The first processor 202 generates the query to extract the media content based on the determined set of rules. Thereafter, the first processor 202 transmits the generated query to the database server 102 by means of the first transceiver 200 to extract the media content including the first set of media content and the second set of media content.

At step 310, the first processor 202 segments the media content including the first set of media content and the second set of media content. The first processor 202 segments the media content of the first set of media content and the second set of media content into the first set of multiple media content and the second set of multiple media content based on at least one of the watch history of the commuter and the journey time between the plurality of locations. At step 312, the first processor 202 extracts the first set of media content and the second set of media content from the database server 102 based on the segmentation of the media content. Based on the segmentation, the first processor 202 extracts the first set of media content and the second set of media content that are more relevant to the commuter with respect to the received first request provided by the commuter.

At step 314, the first processor 202 extracts the media content including the first set of media content and the second set of media content from the database server 102 in the time duration that is based on the first time and the second time. The first time corresponds to a time of confirmation of the received first request. The second time corresponds to a time of boarding of the vehicle 106 by the commuter based on the received first request. Thus, the first processor 202 extracts the first set of media content and the second set of media content from the database server 102 after the confirmation of the received first request and before the boarding of the vehicle 106 by the commuter.

At step 316, the first processor 202 receives the extracted media content including the first set of media content and the second set of media content from the database server 102 by means of the first transceiver 200. At step 318, the first processor 202 stores the received media content including the first set of media content and the second set of media content in the memory 204.

At step 320, the first processor 202 receives the second request from the second processor 214. After the boarding of the vehicle 106 by the commuter, the commuter provides the second request by means of the second I/O port 216. The second request may correspond to a request to play the media content selected by the commuter in the vehicle 106. At step, 322, the first processor 202 controls the playback of the selected media content from one of the stored first set of media content or the stored second set of media content. The first processor 202 controls the playback of the selected media content on the output device 220 of the second device 112 based on the received second request.

At step 324, the first processor 202 receives the third request from the second processor 214. The third request corresponds to a request to extract on-demand media content in the real time or the near-real time. At step 326, the first processor 202 executes the real-time (or near-real time) extraction of the on-demand media content from the database server 102 based on the received third request. At step 328, the first processor 202 updates the memory 204 based on the real-time (or near-real time) extraction of the on-demand media content. Further, the first processor 202 controls the playback of the extracted on-demand media content on the output device 220 of the second device 112.
